Answer:
3.5
Step-by-step explanation:
tan60 = w/2
Multiply 2 on both sides to get the w by itself.
tan60 x 2 = w
Put tan60 into the calculator.
2 x 1.732050808 = w
Multiply.
w = 3.5
Answer:
3x^6 - 4x^5 + 2x^4
Step-by-step explanation:
Given
-5x^4 ( -3x^2 + 4x - 2)
Step 1 : open the bracket with -5x^4
-5x^4 * -3x^2= 15x^6
Hint: - * - = +
x^4 * x ^2 = x^ 4+2 = x^6
-5x^4 * + 4x = - 20x^5
Hint: - * + = -
x^4 * x = x^4 + 1 = x^5
(x is always raise to the power of 1 but we don't write it or less it is greater than 1 e.g. 2 , 3 ,4, ..........)
-5x^4 * -2 = 10x^4
Hint: - *- = +
Let's combine the answers
15x^6 - 20x^5 + 10x^4
We can look for a factor that can go through as in that can divide all without a reminder
Factors of
15 - 3 * 5
1 * 15
20 - 4 *5
2 *10
1 * 20
10 - 2*5
1 * 10
Since the factor of 5 is common in all, so we are using 5 to divide through
15x^6 - 20x^5 + 10x^4
Using 5 to divide through
15x^6 / 5 - 20x^5 / 5 + 10x^4 / 5
= 3x^6 - 4x^5 + 2x^4
945 is your answer but what number blank?
Answer:
Total number of ways are 336.
Step-by-step explanation:
It is required to find the number of ways in which we can award a 1st, 2nd and 3rd place prize among eight contestants. It means we need to find the number of permutations. We need to find
.
Here, r = 3
So,

So, there are 336 ways.
Step-by-step explanation:
<em>given</em><em>,</em>
<em>length</em><em> </em><em>=</em><em> </em><em>4</em><em>x</em><em>²</em>
<em>breadth</em><em>/</em><em>width </em><em>=</em><em> </em><em>y²</em>
<em>we </em><em>know</em><em>,</em>
<em>perimeter</em><em> </em><em>=</em><em> </em><em>2</em><em>l</em><em> </em><em>+</em><em> </em><em>2</em><em>b</em>
<em>so,</em>
<em>2</em><em>(</em><em>4</em><em>x</em><em>²</em><em>)</em><em> </em><em>+</em><em> </em><em>2</em><em>(</em><em>y²</em><em>)</em>
<em>→</em><em> </em><em>8</em><em>x</em><em>²</em><em> </em><em>+</em><em> </em><em>2</em><em>y²</em>
<em>option </em><em>A </em><em>is </em><em>correct</em>
